Nah, that's a fair criticism. The whole "when we get there" can be quite infuriating, more so since vast majority of games doesn't even show up on people's radars (or ask for money) until it's way closer to being done. CIG wanted to share the development process with their players so they have to take both good and bad aspects of such approach.

I definitely feel that unless SC in its current form is something you're willing to put up with, there's no reason to spend any money on it. If something cool comes out of it in the future - nice. If not... well, backers gave them a chance.
